"N" means the time you make the call, nnn.nnn means a specific time which may be different to when you make the call. It's particularly important if the script that collects data and prepares the update takes a long time between collection and update (perhaps some complex conversions). If the script takes very little time to run, the two options are near enough the same in effect. When I wrote the above I wasn't aware you could use decimals in an update time. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
